The goal of Vedic religion is to realize that consciousness (Atman) is actually nothing but Brahman or God in truth.

The Vedic pantheon of Gods is said, in the Vedas and Upanishads, to be the only higher manifestations of Brahman. For this reason, "ekam sat" (all is one), and all is Brahman.

The goal is to realize Atman, which is present in the form of consciousness as the Self.  If Atman or consciousness is nothing but Brahman and by realizing Atman (consciousness) as Brahman or the ultimate truth is truth-realization or Self-Realization, then there is no need to follow the religion, study scriptures or glorify Gods or Gurus and follow the path of doubts and confusion by losing oneself in the labyrinths of philosophy, when there is an easier path. 

By mentally tracing the source of the mind from where it rises and subsides one becomes aware of the fallacy of the mind, which rises as waking or dream and subsides as deep sleep.  The mind arises from consciousness and is subsidies as consciousness.

Brihadaranyaka Upanishad: ~  “The Self is indeed Brahman, but through ignorance, people identify it with intellect, mind, senses, passions, and the elements of earth, water, air, space, and fire. This is why the Self is said to consist of this and that and appears to be everything. 

In the Vedas, God has been described as: ~

Rig-Veda 1-164-46 and Y.V 32-1 clearly mention that God is “One”.

Rig Veda: ~ The Atman is the cause; Atman is the support of all that exists in this universe. May ye never turn away from the Atman, the Self. May ye never accept another God in place of the Atman nor worship other than the Atman?" (10:48, 5)

Yajurveda – chapter- 32:~   God is Supreme Spirit has no ‘Pratima’ (idol) or material shape. God cannot be seen directly by anyone. God pervades all beings and all directions. Thus,   Idolatry does not find any support from the Vedas.

Thus, it refers to formless and attributeless God, which is the Atman (Soul), the   Self within the false experience. Thus it indicates clearly all the Gods with form and attributes are mere imagination based on the false self.  Thus Atman or Soul, the  ‘Self’ is God.

The Vedas do not talk about idol worship. In fact, till about 2000 years ago followers of Vedism never worshipped idols. Idol worship was started by the followers of Buddhism and Jains.  There is logic to idol worship. Vedas speak of one God that is the supreme Self i.e. Atman or Soul but Hinduism indulges in worshiping 60 million Gods.

Yajurveda says: - If one worships anything else as God in place of real God. :~

Translation 1

They enter darkness, those who worship natural things (for example air, water, sun, moon, animals, fire, stone, etc.).

They sink deeper in darkness those who worship sambhuti. (Sambhuti means created things, for example, table, chair, idol, etc.) - (Yajurveda 40:9)

Translation 2

"Deep into the shade of blinding gloom fall asambhuti's worshippers. They sink to darkness deeper yet who on sambhuti are intent. ("Yajurveda Samhita by Ralph T. H. Giffith pg 538)

Translation 3

 "They are enveloped in darkness, in other words, are steeped in ignorance and sunk in the greatest depths of misery who worship the uncreated, eternal Prakriti -- the material cause of the world -- in place of the All-pervading God, But those who worship visible things born of the Prakriti, such as the earth, trees, bodies (human and the like) in place of God are enveloped in still greater darkness, in other words, they are extremely foolish, fall into an awful hell of pain and sorrow, and suffer terribly for a long time." -(Yajur Veda 40:9.)

So, Yajur Veda indicates that:-

They sink deeper in darkness those who worship sambhuti. (Sambhuti means created things, for example, table, chair, idol, etc. - (Yajurved 40:9)

Those who worship visible things born of the prakrti, such as the earth, trees, bodies (human and the like) in place of God are enveloped in still greater darkness, in other words, they are extremely foolish, fall into an awful hell of pain and sorrow and suffer terribly for a long time."-(Yajur Veda 40:9.)

The Hindus believed in polytheism, believing all of their Gods to be separate individuals, which were introduced much later by the founders of Hinduism which contains diverse beliefs caste, and creed. 

 When the religion of the Veda knows no idols then why so many Gods and Goddesses with different forms and names are being propagated as Vedic Gods. Why these conceptual Gods are introduced when the Vedic concept of God is free from form and attributes. :~Santthosh Kumaar
